Blood pressure is normal, what reason is low pressure on the high side

Clinically, low pressure refers to high diastolic pressure, indicating that diastolic pressure is greater than 90mmhg. This situation occurs mostly due to atherosclerosis, such as chronic heart failure, cerebral hemorrhage, hypertensive encephalopathy or cerebral infarction will lead to atherosclerosis. When the peripheral resistance of blood vessels is large, it will also cause low pressure.
